Failed to load map. Error contacting Google servers issue with android google maps api v2 [duplicate]

Answer 1

My solution was use the correct file

in my case i used debug.keystore in C:\Users\.android for generate SH1 KEY

after try meny times, a found anoter file in C:\Users\\Downloads\adt-bundle-windows-x86_64\adt-bundle-windows\sdk.android an use it, for generate SH1 Key

and then copy 45:B5:E4:6F:36:AD:0A:98:94:B4:02:66:2B:12:17:F2:56:26:A0:E0 values the api key site

All Work again
